Packaging and first impressions
The user manual, a warranty note and a heat-resistant mat with integrated storage bag are included in addition to the straightener.
The attached manual was indeed clearly designed, but the hair straightening illustration was so dark printed, that we could not see the marking arrows to the functions and buttons. To be aware of the functions of the individual buttons, the instructions must, therefore, be read accurately.
It should also be noted that, although instructions for heat protection sensor was included, but unfortunately no accurate information on the keratin technology.
Could convince us, however, the high-quality housing that looked modern and innovative.
Furthermore, the heating plates of the Remington S8590 Keratin Therapy Pro close very well.
With 295 g the straightener is the heaviest of all the products tested.
Data, facts, technologies & features
With the turning on of the S8590 straightener the device gave an audible signal and the temperature light was blinking during heating.
The manufacturer’s specification for 10 seconds was referring probably to a lower temperature.
Upon reaching the desired temperature, the straightener beeped again, and the blinking stopped. The display, which did not look like a classic display for us, was new and innovative, but also a bit strange. The numbers are illuminated from behind and displayed directly on the straightener.

Remington S8590 straightener in practice
The Remington S8590 straightener has a temperature range of 160-230°C. The five possible temperature levels initially extended over four 20°C steps and a final 10°C step.
From all tested devices, Remington S8590 has the fewest temperature levels and the unusual temperature steps of 20°C seemed to us too high, as an individual setting to your hair type is, therefore, more difficult.
Also a bar display of the temperature range, which symbolises for which hair thickness which temperature should be set, missing here, unfortunately. This can be found in almost all tested devices.
At smoothing the Remington S8590 performed a good job. The extra-long 11cm styling plates covered during the test even very wide sections of hair easily, and by the resilient hot plates, the straightener pressed the hair lightly.
You can create curls and waves with this straightener, but not perfectly styled, when compared to other tested devices, which probably was due to the more angular design. We managed only to make weak curls in the hair tips, but not over the entire strand of hair.
The Remington S8590 combines two special features: the high-quality Keratin-ceramic coating and the exclusive heat protection sensor, which can be found in a similar form in the Braun Satin Hair 7 ST 780 SensoCare.
They are to prevent hair damage and hair breakage and make hair healthier and stronger. When the heat protection sensor, integrated into the upper heating plate is activated, it continuously detects the level of moisture in the hair and constantly adjusts the temperature to prevent hair damage.
These changes do not appear on the straightener, but quickly and automatically performed during the styling.
Overall, the Remington S8590 Keratin Therapy Pro was a bit heavy, nevertheless, was good in hand and the arrangement of keys for us was clear and easy to handle.
The handle, during the smoothing process, reached approximately 32°C, which we classify as okay. However, the housing around the heating plates was extremely hot with 80-90°C.
A good impression made on us the practical and also visually appealing heat-resistant mat integrated into the straightener bag. Thus, the hot straightening iron can be safely placed on any surface during styling, without damaging it.
The Remington S8590 straightener also features many useful additional functions, such as an automatic shut-off. This is set, as indicated by the manufacturer, to 60 minutes.
Furthermore, the keypad lock and the plates lock represent practical functions. The keypad lock is activated, for example, so that no adjustments are made unintentionally when styling. The plates lock proved to be practical, however, in our opinion, the thin plastic lever quite fragile.
The last function is the so-called “Turbo Boost”. With this, we were able to rapidly increase the temperature to 230°C, to edit, for example, difficult to be shaped strands.
The Remington S8590 Keratin Therapy Pro Straightener is an innovative hair straightener with a unique design that stands out with a keratin protection technology and a heat protection sensor.
It is, therefore, suitable for customers who place great importance on gentler hair smoothing. With a manual setting of 160-230°C, the straightener is more recommendable for medium to thick hair.
Since the Remington S8590, unfortunately, has only five different temperature settings and the housing becomes very hot during the smoothing with 80-90°C, it receives from us a total score of 4.4.
Nevertheless, the S8590 showed a good performance during smoothing. For those who attaches great importance to the making of curls, we recommend the Braun Satin Hair 7 ST 710, which achieved excellent results in that.
